Hydrogen sulfide - in oil & gas exploration

Hydrogen sulfide (H2S) is a naturally occurring gas contained in many of the world’s crude oils. It is also formed in the refining process by the degradation of sulfur-containing compounds in crude at high temperatures.

The average sulfur content of crude oils being processed in the world’s petroleum refineries continues to increase.

Refineries and storage facilities, such as tank farms, are likely to encounter problems specific to the handling of crude oils, intermediates and refined products that contain or generate H2S.

Heavy oils, including crude oil, residual fuel and gas oil, tend to have large concentrations of H2S. This becomes a concern if these products are to be stored for an extended time or during transport.

While safety remains the primary concern when dealing with H2S, other H2S-related issues can create additional challenges for these facilities.
